No. 418,146 Claims priority, application Germany, Dec. 17, 1963, M 46,872 3 Claims. (Cl. 229-55) This invention relates to a packing carton for goods of all kinds, which comprises an open top box including a bottom and side walls and a cover.

Such packing cartons are known in various forms. In most cases their covers engage over the open top box and then project outwardly.

The cover is required to fairly accurately fit the box. After repeated use of the packing carton the side walls of the box become slightly damaged. Furthermore, such packing cartons are expensive in manufacture, especially when the cover is made of a transparent material.

It is the object of the present invention to provide a simple cover having a good seat on an open top box which becomes scarcely damaged even after repeated use.

To achieve this object the invention provides a packing carton for goods of all kinds, which comprises an open top :box including a 'bottom and side walls, a bead on the free ends of said side `walls of said open top box and projecting into the interior of said box, and a cover consisting of flexible material and retained with its edge under said bead.

The cover may consist entirely or partly of a transparent material, e.g. a foil of synthetic plastic material.

It is possible to provide the cover at its edge with a bent-olf portion which may also be partly interrupted. The bent-olf portion at the edge of the cover may extend alternately on one and the other side of the cover.

The packing carton as proposed by the invention may be of any desired form and size. It may have an angular, round, oval or other form.

An embodiment of the invention will now be described by way of example and with reference to the drawing, in which:

FIG. 1 is a cross section through a packing carton according to the invention having a cover;

FIG. 2 is a view similar to FIG. 1, showing a cover with a small bent-off portion;

FIG. 3 is a similar view, showing a cover with a large bent-off portion; and

FIG. 4 is a perspective view of a cover with bent-off portions extending on both sides of the cover.

With reference now to the drawing and particularly to FIG. 1, a packing cart-on as proposed by the invention comprises an open top box 1 including a bottom 8 and side walls 2 and a cover 4. It will be noted -that the packing carton has an entirely smooth outer surface. The side Walls 2 of the open top box have at their -free ends a bead 3 projecting into the interior of the box, which fbead may be formed `by Hanging or rolling over of the sidewalls 2 of the box or may be attached to the side walls. This bead 3 serves for reinforcing the packing carton. The cover 4 consists of a ilexible material, e.g. a transparent foil, and seals a packed article 5 from the exterior. The cover 4 is clamped between the article 5 and the bead 3 and rests with its edge below -the bead.

Fice

The cover 4 may consist of a at foil extending in one plane.

As shown in FIG. 2, a cover 4a has at its edge a ilange portion 6 with which the cover engages under the bead 3. FIG. 3 shows a cover 4b having large bent-olf portions 7 which are supported on the bottom 8 of the box 1. The cover 4b is situated with its major surface below the bead 3.

FIG. 4 shows a cover 4c with llange portions 9 and bent-off .portions 10 extending alternately on one and `the other side ofthe cover.

According to the kind of goods to be packed, a cover 4, 4a, 4b or 4c is used which is in any case retained under the bead 3 of the box 1 and does not engage the packing carton on the outer side thereof.

The invention may `be embodied in other specific forms without departing `from ythe spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

I claim:

1. A container for packaging articles having a bottom Wall, side walls, end walls and an open top, said open top having a removable cover to close said open top, each said side wall having a permanently Iformed crimp constructed from said side wall as an extension thereof at the open end of said container, each said crimp being formed at the time said container is constructed and before the container is filled, each said crimp rising in a rst direction upwardly with the side wall, each said crimp then turning in a second direction inwardly of the container, substantially normal to the iirst direction, each said cri-mp then turning downwardly in a third direction, substantially normal to said second direction and opposite to said first direction, said removable cover lying in a substantially single plane beneath the bottom edge of the crimp and above the packaged article, said removable cover having at least one upwardly extending flanged portion and at least one downwardly extending bent-off portion separate from said flanged portion, said bent-off portions and said flanged portions interspersed about the periphery of the cover so as to wedge said removable cover above a packaged article, and between said crimps, of said container.

2. A container for packaging articles having a bottom wall, side walls, end walls and an open top, said open top having a removable cover to close said open top, each said side wall and end wall having a permanently formed crimp constructed from said wall as an extension thereof at the open end of said container, each said crimp being formed at the time said container is constructed and before the container is filled, each said crimp rising in a rst direction upwardly with the Wall, each said crimp then turning in a second direction inwardly of the container, substantially normal to the first direction, each said crimp then turning downwardly in a third direction, substantially normal to said second direction and opposite to said first direction, said removable cover lying in a substantially single plane beneath the lbottom edge of the crimp and above the packaged article, said removable cover having downwardly extending 'bent-olf portion on at least two sides thereof, the bottom edge of said bent-01T portions being supported on said bottom of said Icontainer while the top edges of said removable cover underlie said container crimps.

3. A container for packaged articles as defined in claim 1 wherein each said end wall also has a crimp constructed therefrom as an extension thereof at the open end of said container.
